How to add more uplink channel (AS923)?

How to add more uplink channel? Currently, I saw only two channel 923.2 and 923.4.
Try to add in region_as923.toml without success.

What exactly did you add, could you share your configuration?

After two regions.gateway.channels.
[[regions.gateway.channels]]
frequency=923200000
bandwidth=125000
modulation=“LORA”
spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=923400000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

I added.

[[regions.gateway.channels]]
  frequency=923600000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=923800000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=924000000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=924200000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=924400000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

[[regions.gateway.channels]]
  frequency=924600000
  bandwidth=125000
  modulation="LORA"
  spreading_factors=[7, 8, 9, 10, 11, 12]

To add under [regions.network]
[[regions.network.extra_channels]]
frequency=9xxxxxxxx
min_dr=0
max_dr=5

Thank you Datnus. Solved.
